To ail whom, it may concern:

Be it known that 1,. ALBERT- EDGAR Kxowmcs, a citizen of Great Britain,and a resident of Wilton Lodge,.' Wergs Road, 5 'icttenhall.Wolverhampton, county of Stafford, England, mana ing director, haveinvented certain new and useful Improvements in. Apparatus for thePurification of Electrolytic threes, of'which the following is aspeeiticati on. y

This invention. comprises improvements in appara tus-t'or thepurification of'electrolytic and has for its object to enable gas ofgreater purity to be obtained and further to render working more secureand'economical, this application being a divisionalapplication of. myapplication 'for patent :for apparatus-for purification of'electrolyticgases,

Serial No. 655647, filed Got. 19, 1911. g 0 The gas may be passed to thepurifying apparatus from an ordinary washer or separator following itsproduction from Water by electrolytic action. On-its way to the puriablemeter and is led to a suitable explosion trap and from that the gas.passes tothe heating chamber or the urifier proper. In its entry intothis cham er the ingoing gas is preheated by the passage around theinlet gas then passes through the contact material actin and t e gas andthe water vapor, formed by. the combination of the gas which is beingpass out to a second trap where the vapor condenses and is removed.From'this'sec- 0nd trap the purified gas passes away through an outletpipe to a suitable collector.

This purifieris used on each half of the electrolytic plant so that inone case the gas collected is hydrogen with oxygen fier the gas may bepassed through a suit radial webs or fins 7a which preferably expipe ofthe outgoing gas and vapor. The

as a catalytic agent instead-of over it collected and the one present asan impurity,-

comprises an outer chamber I) and an inner member 0, the outer chamberis provided with suitable means such as alid d for allowin r access tothe interior and is suitably shape toreceive the inner'or stand member 0and is further provided with a suitable gas iulet. e. The inner or standmember a r is: preferably formed with a cylindrical or other suitablyshaped pillar f which has a flat circular chamber 9 cast or otherwisesuitably formed or attached thereto at a convenient height from itsbase. The circular chamber g-has a deflecting disk hwhich does notextend to the outer wall and this disk is supported by webs i from thetop and bottom surfaces of the chamber 9 so that the chamber is dividedinto radial pockets above and below the disk, with communicationsbetween those below and those above around the periphery of the(llSk'lL, see Fig.

2, and the second quarter of Fig. At the top ofthe chamber gis an outletj leading into the outer chamber 5. On theouter surfaces of the flatcircular chamber 9 are more tend to the inner faces of the wall of theouter chamber- 12. The purifier is suitably heated and this constructionof the'inner chamber through which the gases enter it insures a veryefiicient heatin as the gases are deflected and caused to ibllow deviouspatghs and impinge against the hot ribs and we s.-

Upon the fins or webs 7c gridsl of porcelain or other suitable material.are' placed and upon these the contact material acting as a catalyticagent is spread.- The gases pass down through the contact material pastthe exterior fins k and around the inlet piI-' lar f to the outletconnection. 1a.; Thehot outgoing purified gas and the vapor formed bythe combination of the gaswith the impurity thus assist in heat-ing theingoing gases and ail-effective preheating arrangement is formed. r

The method of supplying heat to the part the present invention.

ing or for heating from a gas or other furnace may be followed and theheating may take place within'the purifier or at the entry pipe to sameaccording to the method chosen. When working is properly in progresslittle or no external or additional heat is required on account of therise of 110 temperature caused by the combination of the gases.

ranged on said Although the construction here shown is a very effectiveone on account of the numerous ribs and surfaces that are provided fortaking up the heat of the outgoing gas and arranged on the exterior ofsaid chambered part.

2. Inapparatus for the purification of gases a heater having a gas inletand a gas outlet, said gas inlet having its orifice in said heater, anenlarged chambered part on said inlet, conducting webs formed on theexterior thereof, and contact material ar webs so that gas issuing fromthe orifice of said inlet passes through said contact material and aftercombination impinges on said conducting webs, heating same and said websconduct the heat to the chambered part of said gas inlet, substanti allyas and for the purpose set forth. I

3. In apparatus for the purification of gases a purifier with an innerchamber, said chamber communicating with agas inlet, an orifice on saidgas inlet arranged above said chamber, webs on'the exterior of saidchamber, said webs supporting grids on which contact material issupported and-a gas outlet from said purifierarranged below said chamberso that gas when is'suing from the orifice of said gas inlet mustpasst-he webs on said chamber onits way to said gas outlet.

4:. In apparatus for the purification of gases a purifier with an innerchamber, said chamber communicating with a gas inlet, an orifice fromsaid gas inlet, said orifice being above said chamber, webs on theexterior of said chamber serving to support grids on which contactmaterial is supported,webs' of the interior of said chamber anddeflecting means causing the incominggas to pass said webs, a gas outletfrom said purifier arranged below said chamber so that the gas issuingfrom said orifice of said gas inlet must pass the webs on the exteriorof said chamber after passing the contact material, said webs thus beingheated and they conduct the heat .to the internal webs 1n said chamberfrom which it is taken upbythe incoming gas, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
